THE SIMO POWER WITH ELECTRIC MOTOR AND DOUBLE HOSE REEL The P 635 SE DHR 20 is driven by an electric motor. Simultaneous operation of two devices (Simo-Power) is possible with the power pack. A higher oil volume ensures a higher flow rate and thus more power. A hose reel module can be retrofitted and quick and safe coupling is possible thanks to monocoupling technology. The P 635 SE DHR 20 is equipped with a 20 m double hose reel (DHR20).
